IMO this thread is a perfect case study for students in business schools. Almost all points of view were presented.
I believe the final conclusion depends on a standpoint, be it customer or manufacurer/dealer.
One thing nobody mentioned is that Lampizator as company is in very fast transition from DIY sector to serious business operation.
If you compare the lampi from 2-3 ago with today's big 7 and GG DACs, there is a real improvement in quality, still not the level of most prestigious hiend brands but with very good P/SQ ratio.
I am sure when Lukasz is back form holidays he will find a solution Ian could accept because he always was very friendly with customers. Now the question is if he can maintain this communication culture when company is growing , organization and HR policy will be crucial.
On the other hand the misunderstanding which arose between a customer and a dealer in a specific country should be dealt by the dealer , this is why the company builds distribution network and do not sale direct ex factory.
I do not see any reason to blame producer for the situation apart from being responsible for organization culture he establish in his network. My only doubt is if the customer when making decision about the audition at home had a good will to keep the unit or just wanted to have opinion about a fancy DAC. On the other hand the dealer should be not so strict about a number of days of the trial period when the expensive product is concerned. Finally, customer is always right and the dealer should bear it in mind.
